摘要
以Cu2+为模板离子,丙烯酸、丙烯酰胺及甲基丙烯酸为功能单体,过硫酸钾为引发剂,二乙烯基苯(DVB)为交联剂,苯乙烯(St)为骨架单体,十二烷基硫酸钠为乳化剂,采用乳液聚合法制备了铜离子印迹聚合物.采用紫外吸收光谱考察了Cu2+与功能单体之间的相互作用,在确定引发剂用量的基础上,考察了功能单体种类、介质pH值、Cu2+/功能单体摩尔比以及DVB/St质量比等因素对印迹聚合物吸附性能的影响趋势,得到了较优的合成条件,并提出了乳液法Cu2+印迹聚合物的合成及识别过程.
The Cu^2＋ -imprznted polymers were prepared from emulsion polymerization using potassium persulfate as initiator, divinyl benzene （DVB） as cross - linking agent, styrene （St） as matrix monomer, sodium dodecyl sulfate as emulsifier, and acrylic acid, acrylamide, methacrylic acid as functional monomers. The effects of Cu^2＋ with functional monomers were investigated by UV spectroscopy. Then with definite amount of initiator, the orthogonal experimentation was applied to investigate the effects of the type of functional monomer, the pH value of medium, the molar ratio of Cu^2＋ to functional monomer and the mass ratio of DVB to St on the adsorbability and selectivity of the prepared polymers. The preferable reaction conditions were obtained, and the synthesis and recognition process of Cu^2＋ -imprinted polymers was sketched out.
